The diversity of rotifers is stunning, and this program shows many different species. Planktonic rotifers have special adaptations for open water life. Nematodes (round worms) include a number of important human parasites, seldom seen but easily found. Thirteen common rotifer species illustrated this diverse group. Tree moss, leaf litter, and compost piles swarm with nematodes.
